Owner approach of sustainability

Qingdao is located at 120°33′E 36°07′N, slightly north of the the Tropic of Cancer. According to the solar energy resources zoning in China, it belongs to the “third types” (with the annual sunshine hours of 2000-3000 h and the radiation of 502-586×104 kJ/（m³·a) and is recommended to use solar energy. The statistical data of the meteorological department shows that Qingdao has few consecutive rainy days, while the annual average sunshine hours is 2541 h, and the annual sunshine radiation intensity can reach more than 1600 kWh per square meter. Therefore, solar PV system is considered suitable from the natural conditions.

In this project, the solar PV system adopted the cadmium telluride thin-film PV glass, a thin-film solar cell based on the heterojunction of p-type CdTe and n-type CdS. The average annual power generation of the system in the first five years can be 43700 kWh, while the total energy demand of the project is only 378000 kWh, which means the renewable energy can supply 11.56% of the total energy demand. At the end of its service life, CdTe components can be recycled to reduce environmental pollution.

In this project, the refrigerant used in the outdoor unit of the multi-split air conditioner is R410A, which is a new type of environmentally friendly refrigerant that does not contain fluorine, with the ODP value of zero, and no harm to the ozone layer.

The water supply source of the project is from the municipal water pipe network, with single water supply at the pressure of 0.25MPa from Jianing Road. The sales office, fire pump room, and fire water tank are all supplied by municipal pressure. The materials involved in the domestic water supply system all meet the sanitary standards for drinking water. The domestic water supply system pipes were flushed and disinfected before being put into use, and the flushing flow rate was not less than 2.0 m/s. After the completion of the pipeline construction, all water pipes were painted with relevant identification paint, and the finish paint was obvious and clear to prevent wrong connection; measures were also taken to avoid wrong drinking and misuse.After the pipes of the domestic water supply system and domestic hot water are flushed, the whole pipe shall be filled with water with the concentration of 20~30mg / L free chlorine, which shall be kept in the pipes for 24h for disinfection. Then, flush the pipes with domestic drinking water, conduct sampling and test by the health supervision department. The pipes can be used only if they meet the current national standard Standards For Drinking Water Quality (GB5749).The domestic drinking water of the project adopted decentralized direct drinking water system, while the raw water is municipal tap water. Direct drinking water pipelines adopt thin-walled stainless steel pipe, and the water production is based on membrane treatment technology. The water quality meets the requirements of the current national standard Water Quality Standards For Fine Drinking Water (CJ945).The toilets in this project all adopted the same floor drainage system with inside wall drainage, which means there is no exposed drainage pipe in the bathrooms. Such design makes the toilets clean and tidy, easy to clean, effectively reducing the drainage noise, the probability of leakage, and effectively preventing the spread of bacteria.The toilets in the project adopted aluminum alloy or copper floor drains that effectively prevent the backflow and dryness; drain covers are chrome plated products. The installed sanitary appliances have water traps in the structure, and the water seal is no less than 50 mm. It is strictly forbidden to use movable mechanical seal instead of water seal. During the operation of the project, the property management unit will test the domestic drinking water and direct drinking water once a quarter.
